Error Message:

DNS Server attempted to cache resource record to a CNAME node. CNAME must be the only record for its domain name.

Explanation:

The two CNAME aliases listed in the error message contain references to each other, creating a CNAME loop. CNAMES allow you to use more than one name to identify a host.

User Action:

Delete one of the CNAME records from the database file: 1. In DNS Manager, double-click the specified file. 2. Right-click one of the specified CNAME records in the right pane, and then click Delete Record. 3. Click DNS on the menu bar, and then click Update Server Data Files.
